building solr dictionary index

Question

I am using FileBasedDictionaryIndex. I have two files. I have set up searchcomponent in solrconfig with Standard request handler and also defined a new field type in schema with appropriate filters.

I want to know whether solr automatically builds index for the dictionary or do I need to write any code (I am using Java) for build Dictionary Index.

Answer 1

SpellCheckComponent can be configured to automatically (re)build indices based on fields in Solr index when a commit or an optimize is done. See http://wiki.apache.org/solr/SpellCheckComponent

UPDATE: I edit this post after seeing the exchange about this topic on SOLR user list: the FileBasedDictionaryIndex needs a spellchecker.build command issued at least once (basically ignore the build / optimize trigger defined on solrconfig.xml)

Answer 2

I entered this url to build spell check index.

http://localhost:8080/solr/select?   q=*:*&spellcheck=true&spellcheck.build=true&buildOnCommit=true

I got this result

<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">0</int>
<lst name="params">
<str name="spellcheck">true</str>
<str name="q">*:*</str>
<str name="buildOnCommit">true</str>
<str name="spellcheck.build">true</str>
</lst>
</lst>
<result name="response" numFound="0" start="0"/>
</response>

I am not getting why my index is not built.

Answer 3

My solrconfig is as below - 

<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">text_spell</str>

<lst name="spellchecker">
   <str name="classname">solr.FileBasedSpellChecker</str>
   <str name="name">file1</str>
   <str name="sourceLocation">places.txt</str>

   <str name="characterEncoding">UTF-8</str>
   <str name="spellcheckIndexDir">./spellchecker1</str>
   <str name="buildOnCommit">true</str>
 </lst>

 <lst name="spellchecker">
   <str name="classname">solr.FileBasedSpellChecker</str>
   <str name="name">file2</str>

    <str name="sourceLocation">US.dic</str>
   <str name="characterEncoding">UTF-8</str>
   <str name="spellcheckIndexDir">./spellchecker2</str>
   <str name="buildOnCommit">true</str>
 </lst>

</searchComponent>

Please correct me.
